IMPROVEMENT IN SODA-WATER APPARATUS.'

Specicatlon forming part of Letters Patent No. 187,416, dated AFebruary 13, 1877 application filed January 3, 1876.

To all 'whom it may concern:

Be it known that I, OTTO ZwIETUscH, of Milwaukee, Wisconsin, have invented certain new and useful Improvements in Soda-Water Apparatus, ot which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of this specification, in which- `Figure lis a vertical section of my invention. Fig. 2 is a sectional view of the pressure-equalizer. Fig. 3 a section, showing parts not shown in Fig. 1. Fig.4is a sectional view, showing arrangement of parts operating rod D.

The object of my invention is to make a new apparatus which serves for the` triple purpose, namely, to make soda-water, to preserve beer, and to act as a chemical fire-extinguisher, for each of which purposes a separate and different machine has heretofore been used.

This result is obtained by the peculiar construction of the machine, as I may use it for any of the above-named purposes exclusively, or for any two of them, or for all three at the same time, with one charge, by means of a self-regulating liquid-addin g arrangement, by the automatical mixing of the chemical ingredients, and by the two self -regulating pressure arrangements, piston-weights, and equalizer, as hereinafter will be described.

In the drawings, A is the generating-chamber, which mayr be made of any suitable material.V B is the cover, withacylindrical opening at the top. O is the piston, that moves in the cylinder extending on cover B, having its packing tightly closed by the internal produced pressure. D is a rod, which is moved out and inward-outward by an internal pressuse, and inward by weighted lever J, to which piston O is connected. It has an agitator, E,at the bottom, a crank, Gr, at the top, and a groove, H, between the crank G and piston C, in which pins I of the lever J are situated, working in a manner that the rod D is allowed to move up and downward, and permitting, at the same time, the revolution of said rod. K is the guide for rod D. L is a' Vessel, connected with generating-chamber A on the outside, and made of material that will withstand acids, having a exible outlet, M,

. extending through swivel Fin the interior of generating-chamber A, which allows the outflowW of the acid as soon as it is brought below the level ot' the liquid contained in said vessel, which outilowis stopped as soon as it is brought above the level by means of rod D. N is a tilting vessel inside of generating- `chamber' A, pivoted in hangers which are attached to cover B, N having an inlet and a bende'd outlet, which extends through swivel F, and through which the contents' of the vessel is 4allowed to iow as soon as the outlet is brought below the level of the liquid, and.4 stopped again when brought above its level by rod D. O is the inlet for vessel N., which is closed by a block-screw. P is the inlet to generating-chamber A Q, inlet for vessel L; R, cqualizing-pipe from generating-chamber A to vessel L; S, stop-cock between generating-chamber A and vessel L; T, outlet and cock, which permits the escape of the liquid from generating-chamber A, when used for the purpose of extinguishing re. U is a hose with nozzle attached. used for the purpose of conducting the liquid from generatingchamber A. Vis the outlet for refuse of generating-chamber A. W is the-gas-puritier; X,

the outlet-pipe from generating-chamber A to purifier W, having a small check-valve, which prevents the water from running back; X', the stop-cock through which the contents of purier W can be led into the generatingchamber A. Y is the inlet through which the purifier Wl is iilled; Y', the outlet for refuse of puriier W 5 Z, the gage for indicating the pressure. let or escape of gas. bis a gas-reserve or fountain5`c, a stop-cock on gas-reserve; d, joint and outlet on same to gas-reserve; e, outlet of pressure-equalizer, from which gas is led to the beer-casks described in Fig. 2.

Fig. 2 is a sectional view of the pressureequalizer, which consists ot piston y, (constructed same as piston (5,) vent h, spring i, screw-cap k, inlet l, and outlet e.

Fig. 3 is a sectional view, having `following parts not shown in Fig. l.- T is an escape-cock for gas, which is tobe used for the purpose of'extinguishing tire. F is a swivel, which holds and carries the outlet of vessels L and N. E is an agitator having twisted wings. J is alever rrxcn.

a is a cock on purier for the outn* (bails) for lever J; p, brace which is placed beneath lever J to bring apparatus out of action.

Fig. 4 is a sectional view, showing the manner in which rod D is operated, with a rubber cover, that may be substituted for the piston C. L is 'the vessel, having a iiexible outlet, m', from which the flow of the liquid is regulated-by means of rod D, which causes a fork, g, to press on the flexible outlet, thereby stopping the iiow, which is opened again when it is released therefrom. N is a vessel, closed by a plunger, r, which is connected to rod D by lever s through slott. a is a rubber cover, suitably attached, to which rod D is connected. c is a double-rolled spring, which maybe sfubA stituted for weight a. w is the guide for lever J.

To operate this machine it is charged with sulphuric acid and bicarbonate of soda dissolved in water; but any other acid or carbonate may be substituted. To fill it, brace p is placed beneath lever J, so that the outlet of vessels L and N are brought up above the level of the contents, whereby the outiiow is stopped. Strong acid or acid diluted with water is put into vessel L through opening Q,

and bicarbonate of soda and water into generating-chamber A through opening P; or acid may he put into either of the vessels L and N and carbonate solution in the other. Then water, with a part bicarbonate of soda, is

put into the puriher W. `It is an advantage to.

put bicarbonate of soda into purifier W, for should any acid part be carried over into it, it will there be neutralized immediately by coming in contact with the water saturated with the soda, and thus prevented from passinginto the cask containing the beer, or in to the fountain which is to Abe charged. By allowing lever J to sink downward, previously properly weighted with weight u, the ingredients of therespective vessels will flow out and come in contact in generating-chamber A, whereby carbonicacid gas is immediately generated, and as soon as the desired pressure is obtained, agitating-rod D is carried outward through this medium by acting from the interior against piston U, Fig. l, or

lcover-u, Fig. 4, causing the iiow of the liquids contained in the respective vessels to cease. As soon as the pressure diminishes, the weighted lever presses downward upon rod D, allowing` the liquids to dow again, and while rod D moves up and downward the contents below are stirred by the wings E, as showii in Fig. 3, and by this performance an automatical mixing of the chemical materials, as also an automatic-acting pressure-regulation, is obtained. The machine can then be used for the following purposes:

l'. As a soda-water apparatus. In using it as such, connect a fountain to outlet d, prop erly filled with water, having valvev h closed in pressure-equalizer By bringing spring t' out of action, to raise the necessary gas, lever j is pressed downward, whereby a greater quantity of liquid ilows into generating-chamber A, which is agitated well by turning crank G on rod D, the result of which will be a high pressure in a very short time, that is led 0E to the fountain till sufficiently charged.

2. As a beer-preserver. To preserve or draw beer or any otherfermented liquid, I convey the carbonio-acid gas to the upper surface of the beer, so as to prevent the entrance of atmospheric air into the cask. No such high pressure is needed as when used for the purpose of 1 making soda-water, and the pressure here' being regulated by attaching more or less weight u to leverj;v but as a higher pressure than that which is required for the preserving and draft of the beer will sometimes be contained inv the apparatus-for instance, just immediately after charging soda-water-then I use the pressureequalizer f. (Shown in Fig. 2.) This pressure-equalizer works as follows: Inlet l is connected to the high-pressure-containing chamber, outlet e to the pipe leading to the beer-cash. The self-closing piston g, to which the vent-plug h is fastened directly, is pressed downward by spring z', which v opens the vent h, so that the gas can pass through this and outlet e to the surface of the beer. As soon as a desired pressure is in the beercask, the gas will press the piston g backward, so that vent h is closed by the plug, andno more gas is allowed to pass through same to the beer. As soon as beer is drawn, or the pressure in the cask is diminished, piston gis pressed down bya spring, t', and vent h opened again, and continued open until it is closed by the counterpressure from the cask. More or less pressure for the beer may be obtained through the medium of cap c, in screwing it down more or less, and by this arrangement a constant and equal pressure of gas is always on the beer, no matter what pressure the supplying-vessel holds. By using this apparatus to carry and press the beer from one story to another, which is now done extensively, and

mostly by air-pumps or hydraulic pressure, a

somewhat greater powerabout sevenrto ten pounds to the square inch-is necessary 5. and to press the beer up withou-t interruption, even when the materials in the generator give out, then I use the gas reserve or fountain b. (Shown in Fig. l.) This gasreserve b is filled with gas immediately after the apparatus is charged by opening cocks a and c. gage Z shows a pressure of about one hundred pounds to the square inch, the reservoir is sufficiently filled; then close cock c, and hold it closed until the materials of the generator are exhausted, when cock at is closed and cock c is opened; the beer will then be supplied from the gasreserve While the generator is being refilled.

3. As a fire-extinguisher, the contents or the product therefrom may be used in three different ways, as follows: It is necessary to ll -only one vessel with acid. The water andsoda When the gredients below thoroughly. :value to agitateit, for it is saturated then with lorgne s carbonicacid gas quicker and better, which is y not the case with other fire-extinguishers. where the acid is `simply added to the bicarbonateofsoda solution. Iconsequently obtain with the same material as others use a 'better carbonated liquid, and in shorter time. By opening gcock T, the contents will discharge and may be used. It can further 4be operated as a chemical fire-extinguisher, without any interruption, by putting cocks on equalizingpipes R and X, sothat the two -outside vessels L and W-may be shut off from the generatingchamber A. As soon as the two mentioned vessels are empty, close their respective cocks which lead their contents to generating-chamber A, and the two proposed cocks in R and X, ill the tank L with acid of standard strength or diluted, and put water and soda into purifier W. During this time the contents of generatingchamber can escape. After it has escaped, open the respective cocks of vessels L and W, when it is again ready for use, and an uninterrupted and steady working is obtained by this arrangement. To use the machine in another manner as a lire-extinguisher, gas-outlet T1 (shown in Fig. 3) is necessary, and a high and constant pressure of carbonio-acid gas is required to extinguish the Y fire. It is known that no fire will burn when atmospheric air contains a certain per cent. of .carbonio-acid gas. Often the fire is in small apartments, or between the, walls, door, or roof, Snc., where it cannot easily be reached with water; and when it is used, damage is done by it, and sometimes to a large extent. By having a small hole, into which the nozzle of the discharge-tubing connectedon cock T can be led, the apartment or place willbe iilled with carbonic-acid gas, and the fire oppressed and extinguished without the use of water.

4. As a soda-water apparatus and beer-preserver, charge a soda-water fountain as described in l, and preserve the beer with the `carbonio-acid gas coming through pressureequalizer f. When the fountain is charged, the remaining gas in the generator is used continually for the beer, which gas is most generally lost when a fountain is charged in the ordinary way.

5. To use it as a soda-water apparatus and chemical tireextinguisher, charge the fountain 'as described in 1, and in case of fire, simply open cock X on purifier W, to let. the water containing soda enterthe generatingchamber A; pressdown lever J, and turn on crank Gr, so that the acid and soda and remaining materials of generating-chamber are well mixed It is of greatA and agitated. When sucient pressure is ob tained, let lever J move upward and open cock T to extinguish the tire.` p

6. As a beer-preserver and chemical tire-extinguisher. scribedin 2, and in case of iire as describedin. 7. To use it for the triple purpose as a soda-water apparatus, beer-preserver, and` chemical fire-extinguisher, attach V lirst the soda-fountain in place of gas-reserve b, charge it as described in l, lead the gas for the beer through pressure-equalizer f, properly regulated, and when the fountain is charged, disconnect it and place gas-reserve b in its stead. In case of tire, operate the machine as described 4in 5, and if carbonio-acid gas is wanted for extinguishing purposes, and the materials are exhausted, refill same as described in 3.

' In the abovedescriptions, it will be seen that gas is taken and used for several purposes, and the remaining materials for the purpose of extinguishing tire. Acid is continually in one chamber and water and soda in the other, which, when coming together, is sufficient to drive out the whole contents of the generating-chamber. Another valuable advantage contained'in this machine is, that it being continually used and charged, and that the parties handling and operating it are thoroughly acquainted and familiar with its operation and working, thushave confidence in it, and in case of a tire are not afraid to use it, and know what is to be done; where, on the contrary, it is often the case that other extinguishers stand in a corner untouched for years, and, when accident of lire happens, are not confidently handled, not knowing how they are operated.

This apparatus can also be built so that one or more vessels of L or L are attached to the outside ofgeneratingchamber'A, or one or more of vessels n or n', inside of generatingchamber A, the outlet of which and their flow being governed by rod l). The doublerolled spring o (shown vin Fig. v4t) I use if a high pressure is wanted in the apparatus, and

where but a short motion of rod D is neces-V sary to shut the outlet oi' the acid-vessel, or

also use it for tire-extinguishing purposes, as

is described in l. The spring is a doublerolled one, whereby it receives double strength, and is more durable than a single-rolled one. The eyes on the ends cannot open, as on one end it is solid, and the other made strong, in an easy manner. The ends on a single-rolled spring easily open, bend, or breakand then the first coil gives out; it extends itself easily, which is avoided in this one, as the power always lies on the eyes and spring centrally.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l.'In a carbonicacid-ga-s generator, or a chemical nre-extinguisher, the self-regulating arrangement, composed or consisting of the in and outward moving rod D, by means of a As a beer-preserver, use as de-` i together by bringing the outlets of the liquidcontaining vessels below their level, and the adding of which is stopped when the outlet is brought above their level by the within produced pressure` as specified.

3, Gas reserve or fountain b, in combination with a carbonic-acidgas generator so arranged that, by drawing beer with carbonicacid gas, the beer receives the gas from said 'gas-reserve, during which time the generator is refilled, and there is no interruption in drawf g, vent h, spring t', and cap k, for the purpose herein set forth.

5. In a carbonic-aoid-gas generator, an agitator, E, in combination with rod D, which works up and downward, and which is so arranged that it may be revolved at the same time, as specied.

6. On a carbonic-acid-gas generator, in combination with the generating-chamber A and purier W, connecting-cock X between chamber A and purier W, to allow the contents of purifier to run into generating-chamber at will,

as specified.

7. Lever J, in combination with pins I, and the groove H, and rod D, as specified.

8. Tilting vessel N, in combination With swivel F and rod D, as specified.

9. Vessel L, flexible outlet M, (shown in Fig. 1,) in combination with swivel F and rod D, as specified.

l0. Rod D, in combination with crank G, swivel F, and agitator E, as specified.
